When it’s time to get a new furnace, there are several things you should think about before making a decision on a particular replacement furnace. With your space and your family’s needs in mind, Morgner Inc. Air Conditioning & Heating can help you select the furnace that will keep your home warm and comfy.
One of the first aspects you need to decide is which fuel source your new furnace will use. The majority of furnaces in North America run on natural gas, but some homes are set up to use liquified petroleum gas, propane or even electricity. It’s important to know which type of fuel is needed for your new furnace.
You’ll also want to consider which type of furnace you’d prefer to appropriately meet your needs. Furnaces are offered in single-stage, two-stage or variable capacity models. A single-stage furnace blows heat consistently at one speed and isn’t the strongest in efficiency within these options. A two-stage furnace is a good fit for many homes. Stage one of a two-stage furnace works at about 65 percent of its capacity, and stage two will kick in for a heating blast on the chilly St. Louis days. But if you want to go for the ultimate choice in flexibility and efficiency, a variable capacity furnace may be a good option.
Unlike single- and two-stage models, variable capacity furnaces don’t have a certain number of stages to go through to create heat. A variable capacity furnace can actually work at different capacities to meet your heating needs.
Whether you want to include a zoning system with your replacement furnace is another consideration. You could save money by more efficiently using your furnace to heat the areas you regularly use, rather than trying to keep the whole house at the same temperature. If you want more to know more about zoning options for your home, Morgner Inc. Air Conditioning & Heating can help.
Another key part of selecting the best furnace for your home is ensuring it’s the proper size for your house. If your furnace is too large for your home’s heating needs, it will waste a lot of energy constantly cycling on and off. If your furnace is too small, it won’t be able to provide adequate heat on the coldest St. Louis days.
Last, but certainly not least, you need to consider your furnace’s energy efficiency rating. A furnace’s efficiency is measured by annual fuel utilization efficiency (AFUE). This rating represents the ratio of annual heat output of the furnace compared to the total annual fossil fuel energy it consumes. For example, an 80 percent AFUE rating means that 80 percent of energy in the fuel heats the home and the other 20 percent escapes through places like the furnace venting. A high-efficiency furnace will have an AFUE rating of 90 to 98.7 percent.
